Confidence intervals. Introduction to confidence intervals : Confidence intervals Estimating a population proportion : Confidence intervals Estimating a population mean : Confidence intervals.

  • The Voyage of the Beagle;
  • Introduction to R!
  • RPubs - statistical-inference:Part 2-Basic Inferential Data Analysis Instructionsless.

More confidence interval videos : Confidence intervals. Significance tests hypothesis testing. The idea of significance tests : Significance tests hypothesis testing Error probabilities and power : Significance tests hypothesis testing Tests about a population proportion : Significance tests hypothesis testing. You will learn concepts necessary to define estimates and margins of errors and learn how you can use these to make predictions relatively well and also provide an estimate of the precision of your forecast.

  • The gaucho Martín Fierro.
  • Explore Library of Case Studies!
  • Causation and free will!
  • Data analysis and statistical inference : A quick guide.

Once you learn this you will be able to understand two concepts that are ubiquitous in data science: confidence intervals, and p-values. Then, to understand statements about the probability of a candidate winning, you will learn about Bayesian modeling. Finally, at the end of the course, we will put it all together to recreate a simplified version of an election forecast model and apply it to the election.
